## EvalCore

EvalCore solves a common failure mode in AI engineering: you tweak a prompt, swap a model, or bump a dependency, and something quietly breaks in production. Instead of trying to re-run expensive, non-deterministic model calls in CI, EvalCore treats AI behaviour like a snapshot. An eval is just a YAML file describing a target and a JSONL dataset, with scorers stacked on top to define what "good" means.

The first run happens live against a real model — anything OpenAI-compatible, vLLM, Ollama, a custom REST API, a shell command, or OpenTelemetry/OpenInference traces. Every request and response is written to a local SQLite cassette, keyed by a hash of the canonical request, along with token and cost figures on the summary. From then on, CI replays those recordings byte-for-byte with `--cache replay`: no network, no API keys, no flaky judge model, and identical inputs always produce identical verdicts.

Because the cassette is committed to your repository, a `--baseline main` comparison fails only on genuine regressions, and the process exit code gates the pipeline. Trials, model comparisons, agent traces, gates, and reports are all a few lines of YAML or a flag rather than a framework. It ships as one small Rust binary, works with any language on the other side of the target, and collects no telemetry.

**Pricing & Plans:** Free and open source under the Apache-2.0 licence, with $0 cost in CI thanks to offline cassette replay. Install via cargo or prebuilt binaries; no signup, no server and no telemetry.

- **Record once, replay forever:** A live run captures every model request and response into a local SQLite cassette that CI can replay offline and deterministically at zero cost.
- **Anything can be a target:** Point EvalCore at OpenAI-compatible endpoints, vLLM, Ollama, your own REST APIs, shell commands, or OTel/OpenInference traces — no SDK required.
- **Scorers that define 'good':** Stack contains, judge-rubric and other scorers in YAML to express exactly what a correct answer looks like for each case.
- **Regression gates and baselines:** Compare against a baseline branch so only real regressions fail, and let the process exit code gate your pull requests.
- **Cost, tokens and reports built in:** Every summary reports token usage and spend for live runs, while trials, model comparisons and history give you a clear picture over time.

**Strengths:** Genuinely free and open source under Apache-2.0, with no usage-based pricing; Deterministic offline replay removes flaky, expensive model calls from CI; Single dependency-free binary that works regardless of your app's language; Configuration is plain YAML plus JSONL, so suites are easy to review and version

**Limitations:** Requires a Rust toolchain or a prebuilt binary and comfort with the command line; Cassettes must be recorded live first, so initial setup needs real API access; No hosted dashboard — results and history live in your repo and CI logs

## Napkin AI

Napkin AI takes a different approach to visualization: instead of prompting an image model, you bring your own words. Write, paste, or import text — from a doc, PDF, or notes — and Napkin analyzes the content to generate relevant diagrams, flowcharts, mind maps, infographics, and data charts. A single click on the Autospark icon produces visual options, and you choose the one that best expresses your idea.

Everything Napkin produces is editable. You can change colors, fonts, layouts, and icons, take a visual apart element by element, or swap it entirely. When your idea needs to become a deck rather than a single graphic, Napkin Slides collaborates with you before building, so the result feels like your own work rather than a generic template.

Finished visuals export as PPT, PNG, PDF, or SVG and drop straight into PowerPoint, Google Slides, Keynote, Notion, or a blog. Napkin supports 60+ languages and is aimed at professionals who need clear visuals quickly — project managers, teachers, consultants, marketers, and anyone who communicates complex ideas through slides and documents.

**Pricing & Plans:** Freemium. The free plan includes weekly AI credits, unlimited editing, unlimited file imports (PPT, DOC, PDF, HTML, MD), and unlimited PNG and PDF exports. Paid Plus and Pro plans unlock more AI credits plus PPT and SVG export, custom branding, and additional design options. Full details are on the Napkin pricing page.

- **Text-to-visual generation:** Paste or import your text and Napkin generates infographics, diagrams, flowcharts, mind maps, and data charts that fit your content.
- **Presentation decks:** Napkin Slides collaborates with you to turn ideas into complete, ready-to-present decks rather than static images.
- **Fully editable output:** Adjust colors, fonts, layouts, and icons, reshape individual elements, and match your brand — nothing is locked after generation.
- **Flexible export formats:** Export visuals as PPT, PNG, PDF, or SVG and drop them into PowerPoint, Google Slides, Keynote, Notion, or any tool you already use.

**Strengths:** No prompt engineering — it works directly from your existing text; Generates a wide range of visual types, from flowcharts to data charts; Everything stays editable and brand-matchable after generation; Free plan includes unlimited imports and PNG/PDF exports

**Limitations:** Free plan is credit-limited and some exports (PPT/SVG) and branding options sit behind paid tiers; Visual generation is not yet available on mobile; desktop is still the best experience; Generated visuals still usually need some manual styling to fully match a brand
